' This invention has reference to improvements in hen, houseconstructions and it has for' its principal objectto improve the roostand drop board cleaners thereof.

The invention has for a further object to provide a roost hinged at itsrear end to adapt it to be-raised at its front end and a cleaner barmovable forwardly and rear-, wardly along the drop board to remove thedroppings thereon; means being provided to raise and lower the roost andmove said cleaner bar, and a common operating means being provided tooperate the .roost and cleaner bar operating means.

A further object of the invention is to provide a hen house with a dropboard having an inclined surface and a transversely disposed receivingtrough at its forward end in communication with an opening or openingsin the side walls of the house; a hinged roost overlying the drop board;a cleaner bar movable over the surface of said board; means to raise andlower said roost; means to move said bar, and means to simultaneouslyraise and lower said roost and move said cleaner bar.

That the invention may be more fully understood, reference is had to theaccompanying drawings forming a part of the description, illustrating apreferred embodiment of the invention, in which Figure 1 isacross-sectional view through a hen house showing my invention embodiedtherein, and

Figure 2 is a detail, in plan, of the operating means for the roost andcleaner bar.

Like characters of reference denote corresponding parts throughout thefigures.

In the drawings, the hen house 1, is not unlike houses of this typehaving front and rear walls 2 and 2 respectively, and end walls 4 with asloping roof 5. The front wall having doorways closed by doors 6.

The drop board 7 is inclined upwardly from front to rear, as shown, andextends forwardly from the rear wall 3 to a point removed some distanceto the rear ofthe front wall 2, terminating in a transversely arrangedtrough- 8, at itsfront end, ,co1nmuni*- catingwith an opening or opeingse in the sidewall or walls 4 of the 'hous'e, -Tlie"drop pingscleanedfrom the surface' of the-drop bo ar'd and "deposited in', said troughmay be rein oved therefromby being-swept or raked;

from said trough through the" 5 Opening or openings 93 The drop board-is'elevated at a height abovethe 'fljoorof the house; and its neat-endremoved from the-front wall-to I pro vide scratching space ther'e'beneathi l0 designates a roost, comprising longitudinal boards 11hinged to the rear wall 3 of the house, at 12. Cross roost boards 13connect said boards 11 and the roost provided with rests 14. Said roostis elevated at a suitable point above the drop board and inl(glinell atthe same inclination as said drop oar 15 designates a cleaner bardisposed transversely of the drop board and arran ed to be movedforwardly and rearwardly t ereof over its surface to scrape the latterand remove droppings thereon into the trough 8, referred to. To said barare connected chains 16 which lie above and below the drop board 7,passing over wheels 17 journaled at the rear end of said drop board andconnected to drums 18 secured to a shaft 19 disposed transversely of thedrop board and at the front end thereof. Connected to said shaft is achain 20 which passes up and over a guide wheel 21 suspended from theroof 5 and down and is connected to the front end of the roost 10. And22 is a preferably short operating shaft journaled in suitable bearings23 secured to the front wall 2 and on said shaft is a sprocket wheel 24which is connected by a chain 25 with a sprocket wheel 26 on the shaft19. A crank 27 is connected with one end of the shaft 22 to operate thesame.

In operation, with the roost and cleaner bar in the positions shown infull lines in Figure 1, and it being desired to clean the droppings fromthe drop board, the operator or attendant will actuate the shaft 22which will impart rotation to the shaft 19 moving the upper runs of thechains 16 forwardly dragging the cleaner bar 15 over the surface of thedrop board and cleaning said board of droppings, which are deposited inthe trough 8. Simultaneously with the forward movement of the cleanerbar, the roost is elevated, as shown in dotted lines. Reversing theoperation of the shaft 22 will move 1.
